Seattle Heatmap

Dec 31, 2017 data

Seattle is a wonderful city dotted with mediocre Starbucks coffee shops, Amazon construction
sites and a beautiful coastal line obscured by the majestic Alaskan highway. After living downtown
for over a year, I aggregated my phones location data and plotted the logarithm of the
recorded location count:

If I plot the radial distance away from my home on a semilog chart, a
linear fit gives an exponential diffusion length (average distance away from home)
of 2.1km - which falls perfectly inline with a person who hasn't owned a car in
over a decade!
